I am looking for the most efficient design for controlling one output with any one of six inputs. This is to run a 12 v solenoid, 12v in, 12v out. 3 amp would be plenty but prefer to overbuild. Six 1N5400s??
Yes.Now, I'm going ask... Is there a simpler, "less clean" way to do this?
Hello DG,Again, I really appreciate that spec. Neat and clean with all of the safeties, Going to go ahead build one and play with it.
Now, I'm going ask... Is there a simpler, "less clean" way to do this? My 12v source is a car battery/alternator, my load is a continuous duty starter solenoid running a motor/hydraulic pump. As you might assume, I will have six individual functions that will require the hydraulic pump to run. These functions will be run by toggle switches switching the +12v...the solenoid along with everything else will be chassis grounded. Noise will probably not be an issue.. Now you're probably going to say, wow this guy wasn't worth my time and I apologize for that but when I said six 1N5400 in my first post, I was somewhat serious. Can I tie the six Cathode ends of the 1N5400 diodes together with the load and use the six Anode ends as my inputs? Some diodes, heat shrink and terminal connectors in my wiring harness and done... I should add that the run time of each function will be less than 5 min, probably more like 1 to 2 minutes. Also it is probable that more than one input could be used at any one given time.
OK- got the fact that you think that the coil is 1A and not 3A, so the 1N5400 diodes will be adequate (by the way the 1N5400 is obsolete). But the diodes must be in free cool air and not covered in insulating material.Again, I appreciate everyone's input and apologize, should have been more descriptive to begin with..and the word "efficient"wasn't the best choice of words. For some reason I can't quickly find the current draw for the coil on the solenoid but my guess is around that 1 amp area. As mentioned I want to overbuild.. I guess a Bosch type relay with a separate source could be added if necessary.
